Description

Technical Field

[0001] This utility model relates to the technical field of hydrometallurgical production, and in particular to an extraction device for eliminating static electricity. Background Technology

[0002] In the nickel-cobalt hydrometallurgical production process, the solution is usually purified by solvent extraction to meet the solution specifications required for producing battery-grade nickel sulfate or electrolytic nickel. Currently, the most common materials for extraction clarification tanks are PVC laminate and fiberglass (FRP), while some high-flow copper extraction processes use clarification tanks with a concrete-lined fiberglass anti-corrosion layer.

[0003] The above three extraction clarification boxes are mainly for clarification and do not consider the safety of the extraction production process. During the extraction process, the solution flows rapidly in the pipeline, which will generate static electricity due to friction. If the static electricity cannot be eliminated, it may cause a fire, resulting in a major safety accident and economic loss. Therefore, this utility model develops an extraction device to eliminate static electricity generated during the extraction process, so as to ensure the safe, stable and long-term operation of the extraction production line.

[0043] Example 1

[0044] refer to Figures 1 to 4 To address the issue of static electricity generated during solution transportation, the specific technologies are as follows:

[0045] By setting a speed reducer 4 at one end of the connecting pipe 13, the motor 6 drives one of the transmission wheels 42, which, in conjunction with the transmission belt 43, drives the other transmission wheel 42 to rotate.

In a dry environment with humidity <40%, the air has strong insulation and static electricity is easy to accumulate. When the humidity is >50%, the air conductivity increases and the charge is quickly conducted to the ground through the water molecules in the air, reducing the risk of electrostatic discharge.
